# verify

> Verify contracts deployed on MegaETH testnet or mainnet

# mega verify

The `verify` command submits contract source information through Foundry's `forge verify-contract`.

## Usage

```bash theme={null}
mega verify <address> <contract> [options]
```

## Arguments

| Argument   | Description                                                     |
| ---------- | --------------------------------------------------------------- |
| `address`  | Address of the deployed contract                                |
| `contract` | Contract path and name, such as `src/MyContract.sol:MyContract` |

## Network options

| Option                | Description                                     |
| --------------------- | ----------------------------------------------- |
| `--network <network>` | Select `testnet` or `mainnet`                   |
| `-r, --rpc-url <url>` | Override the selected network's default RPC URL |

Although the shared network option defaults to `local`, local contracts cannot be explorer-verified. Pass either `--network testnet` or `--network mainnet`.

## Common options

| Option                         | Description                                    |
| ------------------------------ | ---------------------------------------------- |
| `--verifier <name>`            | Verification provider; defaults to `etherscan` |
| `--verifier-url <url>`         | Custom verifier API URL                        |
| `--etherscan-api-key <key>`    | Etherscan API key                              |
| `--constructor-args <args>`    | ABI-encoded constructor arguments              |
| `--compiler-version <version>` | Compiler version used for deployment           |
| `--watch`                      | Wait for the verification result               |

## Examples

### Verify on MegaETH testnet

```bash theme={null}
mega verify 0xContractAddress src/MyContract.sol:MyContract \
  --network testnet \
  --watch
```

### Verify on MegaETH mainnet

```bash theme={null}
mega verify 0xContractAddress src/MyContract.sol:MyContract \
  --network mainnet \
  --etherscan-api-key <api-key> \
  --watch
```

### Use a custom RPC

```bash theme={null}
mega verify 0xContractAddress src/MyContract.sol:MyContract \
  --network mainnet \
  --rpc-url https://your-mainnet-rpc.example
```

Mega CLI validates a custom RPC's chain ID before invoking Foundry.
